Jennifer Lawrence dined on a stodgy sandwich after the Baftas (Picture: PA)

Exclusive: She may look a million bucks but Jennifer Lawrence proved she has simple needs just like any other girl on a night out with sore feet and the munchies at the Baftas.

After navigating her way up a soggy red carpet and avoiding her ex-Nicholas Hoult at the awards show, the actress wasted no time hitting up the vending machine at the staff café in the Royal Opera house.

A witness said: ‘People were shocked to see her down in the basement. The show had literally just finished.’

‘Jennifer looked exhausted and had whipped of her heels and left them on one of the canteen chairs.’

The barefooted star then moved to sort out her grumbling tummy.

The source said: ‘She asked her entourage for change and was eyeing up crisps and chocolate in the vending machine.’

In the end Lawrence settled for a stodgy old sandwich from the counter, which she wolfed.

‘A photographer who was surprised to find her in the basement asked if he could take a picture and she replied “Oh, come on, looking like this!”’ said the onlooker.

The junk food was enough to fuel on the 22-year-old for the rest of the night as she hit up The Weinstein Company and Grey Goose after party where she found her co-star Bradley

Cooper dirty dancing with 31-year-old Sex And The City 2star Alice Eve.
